' MMERSING nnvron FOR WASHING BowLs.

Application filed September 1924:. Serial N0. 737,727.

To all whom it may concern:

Be it known that I, FRANKL FUnnUsH, acitizen of the United States," residing at I Vestford, in the county of Middlesex and State of Massachusetts, have invented a new and useful Immersing Device for IVashing Bowls, ofwhich the following is a specification. 7

. This invention relates to that type of machines for washing wool and other fibres in which a'rake is used, for pushing the fibres along the bowl from one end to the other and" for pushing them down so that the fibres will be subjected to the action of'the water and will be advanced intermittently.

The principal object of this invention is to provide means, controlled and guided in part by the rake, for ensuring that the fibres at a certain point or points along the rake shall be thoroughly immersed under the surface of the water or other liquid in the bowl at least once during their travel along the bowl from end to end.

Reference is to be had to the accompanying drawings, in which Fig. 1 is a side view of a washing bowl shown with a preferred embodiment of this invention applied thereto, the bowl being broken away to show interior construction;

Fig. 2 is a similar view showing the rake in a different position; and

Fig. 3 is a fragmentary plan of one side of the bowl and one end of thefloat;

As stated, the invention relates to a wool washing machine comprising a long bowl 10 containing the liquor into which the wool or other .iibre is fed at one end and along whichit is carried by (he reciprocation of the rake 11 having teeth'lQ, extending down into the liquor within the bowl. These parts of the ordinary type of wool washing nia.

chines are not changed by this invention but in addition thereto I place in the bowl and under the rake one or more floats 13. These floats are located between two sets of rake teeth and extend across the bowl. They-are designed to float ontop of the liquor .inthe bowl as lshown in Fig. 1 when the rake raised'and to be forced down into the liquor when the rake is lowered as shown in Fig. 2. The object is to thoroughly immerse all the fibres as they pass the; point at which the float is located. Themachine can be made with only one of these fi K PS because all the fibres pass each point and they will all be forced down in at that point if only one of them is used,but I preier to employ aplurality as indicated in Fig. 1..

In construction this float preferably is a water-tight roll cylindrical in shape although it can be of other shapes. It can be made of solid wood or of hollow metal filled with ground cork or any material that will float. I prefer to make it cylindrical so that it will roll along freely on the water without resistance to the rake, but that is not essential.

At the sides of the bowl are a pair of supports or guides 14 each having two verti the rake comesdownon it, it will slide one.

way or the other and the rake will not puncture it.

In the operation ofthe device, when the rake goes down the parallel rails at the top, which constitute the back of the rake, push the roll down into the liquor and also carry it along the full travel of the rake. When the rake moves back on the return motion, it also carries the roll back still in the liquor. If in coming down the rake teeth strike the roll it will roll along on the liquor one way or the other enough to avoid puncture. hen the liquid is drawn off the roll will rest on the bottom of the guides 14 and roll down to the lowest point and then will float when the liquor is introduced. These guides represent the limit of the downward travel of the roll but they do not interfere with it as they are made deep enough to avoid that difliculty. I

Although I have illustrated and described only a single form of the invention I am aware of the fact that modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims.

described but what I do claim is 1. In a washing bowl, the combination with the bowl and a reciprocating rake therefor of u flout in the howl located between two sets of teeth of the rake in posh tion to he moved down into the liquor in the howl hy the descent of the rake and to he moved along the howl by its reeipmeution.

22. In :1 machine for washing wool or the like, the eon'ihiinition with u howl and i1 reciprocating rake, of a cylindrical float loouted at :1 point between two sets of teeth of the rake in :1 position to out and to he pushed down into the liquor by the deseent oi? the rake.

In a wool washing nniehine, the combination with a bowl having; guides at its sides end :1 reeiproeuhle rake, of :1 Heat adapted to float on the liquor in the bowl and having its ends extending into id.

guides to he guided thereby, wherein when the rake descends i; will push the roll down into the liquor and carry it along to imnieree any stoek in that vieinity and whereby when the liquor drawn oil the roll will renmin in the guides ready for use.

In a wool washing inz'iehine, the conihi nution with u howl having guides at its sides and a reeipronhle rake, of u flout adapted to flout on the liquor in the bowl and having its ends extending into said guides to he guided thereby, said guides comprising vertical ends and an inclined bottom.

In testimony whereof I have hereunto affixed my signature.
